Abstract
A resistor includes at least one polysilicon resistor element in a semiconductor substrate with each polysilicon resistor element having a continuous U-shape with a continuous lateral bottom. The resistor may include an insulator within a valley of the U-shape of each polysilicon resistor element. A plurality of polysilicon resistor elements can be sequentially interconnected to create a serpentine polysilicon resistor. The resistor may also include a dopant-including high resistivity (HR) polysilicon layer thereunder to provide electrical isolation from, and better thermal conduction to, for example, a base semiconductor substrate. The resistor can be used in an SOI substrate. A related method is also disclosed.
